How a Australia eSIM compares
Carrier roaming
~€16/day
≈ €224 for 2 weeks
Typical international roaming charge from major EU/UK/US carriers in Australia. Caps often activate after €60/month and throttle to dial-up speeds.
Local SIM at airport
€15 to €40
one-time plus setup hassle
Telstra and Optus tourist SIMs cost €30 to €60 a week at airport kiosks. Activation needs passport plus Australian address (your hotel works) and takes 15 to 30 minutes.
RoamingFlex eSIM
€9.43
3GB / 15 days
Same plan covers 2 weeks of travel in Australia. QR code in under 90 seconds. No app, no airport queue, no passport scan.
How much data you actually need in Australia
Tourists in Australia average 430MB/day. Australian tourist data averages 400 to 470 MB per day. Uber works in major cities, DiDi competes hard in Sydney and Melbourne, and Google Maps handles the road trips. Australian distances are huge and Maps caches matter on long drives. Restaurant booking through Quandoo or directly via Instagram is common. Source: RoamingFlex 22-destination data usage dataset (CC BY 4.0).
Insider tip
Telstra has the only meaningful coverage in the outback. If your trip includes the Red Centre, the Kimberley, or remote Tasmania, the RoamingFlex eSIM routing to Telstra is the difference between "I have data" and "I have a paperweight." For Sydney-Melbourne-Brisbane city trips, Optus is fine.

Australia eSIM frequently asked questions
Will the eSIM work in the outback?
Coverage in the outback depends entirely on Telstra, and even Telstra has gaps. The main tourist outback areas (Uluru, Alice Springs, Coober Pedy) have coverage in town and patchy signal on the access roads. Genuinely remote stretches (Tanami Track, Anne Beadell Highway) have no signal on any carrier.
Does it cover the Great Barrier Reef boat trips?
Coverage on the boat departure ports (Cairns, Port Douglas, Airlie Beach) is solid. Once you're a few kilometres offshore on the reef trips, signal drops to weak or nothing, which is normal.
How much data do I need for a 2-week Australia trip?
10GB is the comfortable answer for an east-coast Sydney to Cairns itinerary. 5GB works if you're city-only. For long road trips through the outback, Unlimited is the safer pick because pre-loading Maps offline only goes so far.
Will it work in Tasmania?
Yes. Hobart and Launceston have full 4G LTE and increasingly 5G. The Cradle Mountain area and the Tasman Peninsula have coverage in town and on major roads. Remote bushwalks (Overland Track interior, Southwest National Park) drop to no signal.
Can I use the eSIM in New Zealand on a side trip?
No. Australia plans are Australia only. For a Trans-Tasman trip, RoamingFlex sells a separate New Zealand plan or an Asia Pacific regional plan covering both.
Does it cover the Indian Pacific train?
Coverage on the trans-Australian rail route is intermittent. The train spends days crossing the Nullarbor where no carrier has signal. You'll have data in Adelaide, Kalgoorlie, and Perth, and not much in between.
